①Conclusion of the rules. 1.

现在完成时的被动语态的结构：

have/has been done 2. 现在完成时被动语态的各种句式：

[肯定式]

have/has＋been＋done [否定式]

have/has＋not＋been＋done [疑问式]Have/Has＋主语＋been＋done? [特殊疑问式] 疑问词＋have／has＋主语＋been＋done

3. 现在完成时被动语态的主要用法

1) 表示过去发生的动作对现在造成的影响与结果。当动词为短暂动词时，可与already或yet连用，但不能与for或since引导的表示一段的时间状语连用。例如：

I’m sorry，but the letters haven’t been typed yet. 很抱歉，这些信件还没有被打印出来。(结果是，现在还拿不到这些信件) The work has already been finished. 工作已完成了。(结果是，现在不用做这项工作了) 2) 表示一个被动的动作或状态开始于过去，持续到现在，并有可能持续下去，常与for或since引导的时间状语连用，或用于How long...？句型中。例如：

The plan has been discussed for nearly 2 hours. 这项计划已被讨论了近两个小时了。

3) 用在时间或条件状语从句中，表示将来某时已完成的动作，即用现在完成时的被动语态代替将来完成时的被动语态。

2) 只有及物动词才有被动语态，不及物动词（词组）没有被动语态, 如:happen, take place, die, appear, disappear, fail, remain, lie, last, sit , stand, break out, come true, belong to等

3) 副词的位置

often, usually, always, never, hardly, seldom等副词置于have/has和been中间。

4 ) 许多不及物动词加介词或副词构成的短语动词，相当于及物动词，也可以有被动语态。但短语动词是一个不可分割的整体，变为被动语态时，不可丢掉构成短语的介词或副词。如：

e.g. A notice has been put up on the wall. 5) 非延续性动词，如borrow，finish，begin，start，buy，marry，open，join等构成的现在完成时的被动语态不能与表示一段时间的状语连用。若要表达相应的意思，则要改换动词或时态。
